A boat cruise Santorini caldera trip runs from 3 hours to 12 hours in the listings, on catamarans, a wooden boat, a motor yacht or a glass-bottom boat. All 12 listings read for this page include food and a pick-up, and nine of them name a swim stop.
Weighing a sea day against a road day or another island, the Greece Tours homepage lists every region and island with tours.
What does a boat cruise Santorini caldera trip actually circle?
A boat cruise Santorini caldera trip sails inside a broken ring of three islands around a flooded caldera. The ring is Thira, Thirasia and Aspronisi. Two dark islets, Palea Kameni and Nea Kameni, sit in the middle and supply the stops.
Wikipedia lists the outer ring as Santorini (ancient Thera), Thirasia and Aspronisi. The uninhabited Kameni islands sit in the centre. Aspronisi means White Island, after the pale pumice on top. It measures 650 metres by 200 metres and has two pebble beaches. Our Santorini caldera guide covers the cliffs above.
Before the Minoan eruption the ring was almost closed, with one entrance between Aspronisi and Thira. The eruption destroyed the sections between Aspronisi and Thirasia and between Thirasia and Thira. That created two new channels. A boat cruise Santorini caldera route therefore circles a ring with gaps in it, not a closed wall.
Wikipedia says at least four partly overlapping calderas make up the bowl. A footnote gives the southern basin as 290 metres deep and the northern basin as 385 metres. The cliffs are 300 metres high on three sides. The four calderas date as follows:
- Southern caldera: about 180,000 years ago
- Skaros caldera: about 70,000 years ago
- Cape Riva caldera: about 21,000 years ago
- Current caldera: about 3,600 years ago, in the Minoan eruption
Every boat cruise Santorini caldera trip sails in the newest of the four, the bowl the Minoan eruption left.
The islets of the route grew in steps. Wikipedia says the first Kameni island broke the surface in the second century BC. Palea Kameni, the Old Burnt Island, formed between that century and the first century CE. The listings name both islets as stops on a boat cruise Santorini caldera trip.
Wikipedia records nine eruptions above water since then. An episode in the early eighteenth century ran just over four years. It built a new island and a lava dome. A nineteenth-century episode of close to five years did the same.
Nea Kameni covers 3.4 square kilometres and is about 2 kilometres across. Three eruptions in the twentieth century centred on it. The first ran about two and a half years and the second nearly two years. Each extruded a lava dome. The last ran 23 days and extruded one more dome. Only fumarolic activity remains.
North-east of Thira lies Kolumbo, a submarine volcano about 8 kilometres from Cape Kolumbo. Its crater is about 1.5 kilometres across. Its last eruption killed about seventy people and set off a tsunami that hit islands up to 15 kilometres away. Researchers found a magma chamber 2 to 4 kilometres below sea level.
Which kinds of boat sail a boat cruise Santorini caldera route?
Seven of the ten listings name their vessel. They are four catamarans, one traditional wooden boat, one motor yacht and one glass-bottom boat. The other three say only sailing cruise or boat cruise. All ten sell a boat cruise Santorini caldera trip.
Catamarans are the largest group among the boat cruise Santorini caldera listings. One describes a 45-foot sailing catamaran on a 5-hour sail. It lists a hot springs visit, a snorkel stop and a view of the volcanic cliffs. Another says the catamaran cruises along the coast and offers a morning or afternoon departure.
A third catamaran sails to Mesa Pigadia and the Red and White beaches. The listing lets guests sunbathe on the deck. The fourth runs 3 hours and is booked as a group of up to 10 people. It passes the two beaches and the volcanic islets and includes a swim.
A traditional wooden boat sails in one listing. The listing says it cruises around the caldera and visits the area’s highlights. The trip runs 5 hours and carries the small-group label. A wooden hull and a catamaran hull both give a 5-hour boat cruise Santorini caldera trip in these listings.
A motor yacht sails in another listing. It runs 3 to 5 hours, and the listing says the guest can create their own itinerary. The yacht is booked as a private group. That makes the boat cruise Santorini caldera route a custom plan, not a set one.
A glass-bottom boat sails in one listing and runs 5.5 hours. It stops at Nea Kameni, Palea Kameni and Thirasia. The listing offers a hike to the top of the volcano. It also offers a swim at the hot springs and free time on Thirasia. It is the longest named-boat listing in the boat cruise Santorini caldera set.
Three listings name no vessel. One is a winter sailing cruise of 5 hours. One is a sailing cruise of 4 to 6 hours. One is a boat cruise of 3 to 10 hours. Only one listing mentions a deck. None mentions shade, a toilet or a swim ladder. The Santorini catamaran cruise page covers the catamaran in depth.
How long does a boat cruise Santorini caldera trip last, and what fits in each length?
The listings state lengths from 3 hours to 12 hours. A 3-hour boat cruise Santorini caldera trip fits the volcano hike, the hot springs and a sunset sail. A 5-hour catamaran adds a snorkel stop. Trips of 7 hours or more add Thirasia and Oia.
Eight listings give a duration and a stop list for the caldera. Five state a range of hours and three state one number. The ranges are 4 to 6, 3 to 10, 3 to 6.5, 6 to 10 and 7 to 10 hours. The single values are 3, 7 and 12 hours.
Three of the eight start at 3 hours. The one with exactly 3 hours lists a hike to the volcano, a hot springs stop and a sunset sail. A short boat cruise Santorini caldera trip is built on those three. The other two stretch to 6.5 and 10 hours. Both mention a hike to the crater.
One listing runs 4 to 6 hours. It lists a hike up to the crater at Nea Kameni. It adds a swim in the hot springs near Palea Kameni and free time on Thirasia. The glass-bottom boat listing from the section above names the same stops in 5.5 hours.
Five of the ten boat listings above state a flat 5 hours for a boat cruise Santorini caldera sail. The three catamarans among them name the hot springs and a snorkel stop. None of the five describes a landing on Nea Kameni.
Four listings state 6 to 12 hours: 7, 7 to 10, 6 to 10 and 12 hours. Three of the four name Thirasia, and three of the four include the sunset at Oia.
The 12-hour listing is the longest. It names four stops: Nea Kameni, the hot springs, Thirasia and the sunset from Oia. One of the four calls itself a full-day tour. That is the long end of a boat cruise Santorini caldera trip.
The widest range, 3 to 10 hours, adds a second swim at Thirasia Bay on the morning cruise.
What does a boat cruise Santorini caldera listing include on board?
Every one of the 12 boat cruise Santorini caldera listings states food on board and pick-up. Nine describe a swim and seven name an open bar. Gear, guides and languages change from one listing to the next.
Food comes first. All 12 listings state a meal or food on board. Six name a barbecue. Three name Greek food, and one of the three adds a barbecue. One lists finger foods and fresh fruit, and three say only that a meal is served. Four describe the meal as fresh, freshly cooked or freshly prepared.
Every boat cruise Santorini caldera listing names drinks in its title or its highlight lines. Seven use the words open bar, and three use the word unlimited. Five name wine, two name beer and one names soft drinks. Two specify white wine, and one more lists a sparkling wine.
The water items come next. Nine listings describe a swim, and nine name snorkelling. Six name Red Beach or White Beach as the place to swim, and one names Mesa Pigadia Beach. Six also list a hot-spring stop. Only one states that snorkelling gear is provided. The other eight name the activity and leave the gear unstated.
Two items never appear in a boat cruise Santorini caldera listing. No text mentions towels, and none mentions life jackets. Both are questions for the operator before the day.
Pick-up comes next, and all 12 listings carry a pick-up label. One summary adds roundtrip transport, which makes it the only listing to mention the return leg. Listings that sail at dusk have their own page, the Santorini sunset cruise guide.
Language and guiding close the list. Eight listings run in English only, and four offer English and Greek. One promises a guide on board who explains the volcano’s history, and one lists an optional audio guide. Three listings mention music on board, and three mention sunbathing.
These counts come from each listing’s title, summary and highlight lines. They show what the listing text promises, nothing more.
How do wind and sea conditions change a boat cruise Santorini caldera trip?
Wind decides the sea on a boat cruise Santorini caldera trip. Force 4 is 11 to 16 knots. Force 6 is 22 to 27 knots. Force 8 is a gale of 34 to 40 knots.
The Beaufort scale links each wind force to a sea state. At force 4 the waves are small and grow longer, with fairly frequent white horses. At force 6 large waves begin to form, and the white foam crests cover more of the sea.
At force 8 the waves are moderately high and long, and their crests break into spindrift. At force 9 the table says spray affects visibility. It gives open-ocean wave heights of 1 to 2 metres at force 4. At force 6 they run 3 to 4 metres, and at force 8 they run 5.5 to 7.5 metres.
The table gives those heights for the open ocean, not along the shore. Read them as the open-water case for a boat cruise Santorini caldera route.
The meltemi is the strong, dry north wind of the Aegean. Wikipedia says it blows periodically from late spring to mid-September. Its article on the climate of Greece says it can blow from late spring to October. The highest frequency falls in July and August. Rain and temperature by month sit on the Santorini weather page.
That article adds that very windy days fall in particular in the Cyclades and around them. Wikipedia says the wind can reach force 7 to 8, which is 28 to 40 knots on the table.
A Greek weather news site describes the sailing ban. It says the local port authorities and the Hellenic Coast Guard issue it, together with the Hellenic National Meteorological Service. It says a ban comes when winds reach very high strength, mainly 8 Beaufort, 9 Beaufort or stronger.
The same site says the ban can cover passenger ships, ferry boats, hydrofoils and fishing boats. It can also cover sailing boats and small leisure craft. The decision rests on wind strength, wave height, visibility and general sea conditions. Ask a boat cruise Santorini caldera operator which of those four readings it applies.
A yacht charter climate guide says the caldera offers greater shelter from certain wind directions. It adds that open passages grow more demanding in strong meltemi, with more wind and wave activity.
All 12 listings carry free cancellation, and none states a wind limit or a weather rule. The wind question therefore goes to the operator. Ask what force stops the departure and whether the trip moves to another day.
What do travellers ask about a boat cruise Santorini caldera trip?
Six short questions come up about a boat cruise Santorini caldera trip. They cover the islands, a landing, a lighthouse, the wind direction, a spell’s length and the wind speed.
Which islands does a boat cruise Santorini caldera listing name?
Three of the 12 listings name Thirasia as a swim or lunch stop, and one names Nea Kameni. Eight name no island. Their stop lines name beaches, hot springs or a lighthouse.
Does a boat cruise Santorini caldera trip land on Nea Kameni?
One of the 12 listings names Nea Kameni, as a snorkel stop, and none states a landing. Wikipedia calls the uninhabited islet a protected scientific site that tourist boats visit daily throughout the summer.
Which lighthouse does a boat cruise Santorini caldera trip pass?
Three of the 12 listings name the Akrotiri Lighthouse. Wikipedia says a French company built it in the nineteenth century, making it one of the oldest in Greece. The Greek Navy recommissioned it after World War II.
Which way does the meltemi blow across a boat cruise Santorini caldera route?
Wikipedia says the etesians, or meltemi, blow from the north over the central Aegean. Over the southern Aegean and the Cretan Sea they blow from the north-west. The direction runs anywhere between north-east and north-west, depending on local topography.
How long does one meltemi spell last on a boat cruise Santorini caldera route?
Wikipedia says etesian winds sometimes last for days without a break. A yacht charter guide agrees: the wind can build during the day and persist for days.
How fast is the wind at force 4, 6 and 8 on a boat cruise Santorini caldera trip?
On the Beaufort table force 4 is 20 to 28 kilometres an hour. Force 6 is 39 to 49, and force 8 is 62 to 74. The scale measures wind speed at 10 metres above the sea surface.
